ALSO, NO FUEL WAS FOUND IN THE AIRPLANE & NO EVIDENCE OF FUEL SPILLAGE WAS FOUND ON THE GROUND, ALTHOUGH THE MAIN FUEL TANK HAD RUPTURED & THE FUEL LINES HAD BROKEN. THE FUEL SELECTOR WAS FOUND IN THE THE RIGHT WING TANK POSITION. THE PILOT'S LOG BOOK WAS NOT FOUND; HOWEVER, ON AN APPLICATION FOR A MEDICAL EXAM ON 7/28/88, HE REPORTED THAT HE HAD ABOUT 10,500 HRS OF FLIGHT TIME. THE PILOT HAD JUST PURCHASED THE AIRPLANE. RECORDS SHOWED THAT HE HAD FLOWN IT EIGHT HOURS SINCE IT WAS PURCHASED.
